Proticia venezuelensis n. g. and sp., based on a partial mandible from rocks attributed to the Trujillo Formation, Paleocene to early Eocene, exposed on the southern flank of the Sierra de Baragua, State of Lara, is described. Proticia is the second colombitheriid pyrotherian to be recorded; it is possibly ancestral to the later Colombitherium. The early pyrotheres are briefly reviewed, and Carolozittelia and Griphodon retained in the Pyrotheriidae; Archaeolophus and Carolozittelia may have...

This paper is the second in a series of two works detailing the descriptive and comparative anatomy of the xenarthran ear region (basicranium and its immediate surrounds, including the middle but not the inner ear). The study was begun by Patterson and Segall in 1945 and continued until Patterson's departure from the Field Museum in 1955, but was never completed. Part I (Patterson et al., 1989) covers the anatomy of the auditory region in cingulates, i.e., armadillos, pampatheres, and...

This report is the first of two planned works detailing the descriptive and comparative anatomy of the xenarthran ear region (basicranium and its immediate surrounds, including middle ear, but not the inner ear). The study was begun by Patterson and Segall in 1945 and continued actively well into 1955, and only fitfully by Patterson thereafter. This part, "Cingulates," covers a representation of the Cingulata (= Loricata), including dasypodoids (Utaetus group, Priodontes group,... Topics: Ear, Xenarthra, Fossil

The complex shape of the leaf called Brittsia problematica suggests a floating life habit. The rachis and the pinna axes are flattened. The pinna axes have lateral lobes extending in the plane of the axes. The pinnules are lacerated and extend out of this plane. Several of the above mentioned characteristics of Brittsia are similar to those described by Phillips and Andrews (1968) from the fertile frond portion of Biscalitheca. Therefore, it becomes more likely that Brittsia is a coenopterid...
